l you say "black race" which is wrong we are all the same race its called homosapien. Ethnicity are different is all. In other words, the so-called “racial” differences are absolutely trivial— overall, there is more variation within any group than there is between one group and another. If a white person is looking for a tissue match for an organ transplant, for instance, the best match may come from a black person, and vice versa. ABC News claims, “What the facts show is that there are differences among us, but they stem from culture, not race.The only reason many people think these differences are major is because they’ve been brought up in a culture that has taught them to see the differences this way. Dr. Douglas C. Wallace, professor of molecular genetics at Emory University School of Medicine in Atlanta, stated, “The criteria that people use for race are based entirely on external features that we are programmed to recognize.”scientists have discovered that there is one major pigment, called melanin, that produces our skin color. There are two main forms of melanin: eumelanin (brown to black) and pheomelanin (red to yellow). These combine to give us the particular shade of skin that we have.Melanin is produced by melanocytes, which are cells in the bottom layer of the epidermis. No matter what our shade of skin, we all have approximately the same concentration of melanocytes in our bodies.

Carbon makes up about 18% of the human body. But, it all depends on whether you're referring to carbon monoxide or carbon dioxide.Since humans are carbon-based (all organic or "living" things are considered carbon-based) beings and most of our macromolecules necessary for life are carbon based as well such as amino acids (which form proteins) carbohydrates (hence carbo- which gives us glucose, sucrose, lactose as well as other sugars) lipids (fats) and nucleic acids. On the other hand there are indeed some carbon-based toxins that your body forms.
